What a devastating chapter... My comment from chapter 73 turned out right but I now feel that the narrative went even further than what I previously though, which I think is really brave from the author.
The narrative doesn't seem to take an easy way out and present a single individual (the father) as the villain and the source of all trouble for the other characters. Yes, the father is an antagonist but even he appears to have been the "victim" (I don't know how I feel about being this charitable towards this twat) of the real antagonist of this story, tradition and the fucked up culture these people were all raised in. In this chapter we found out that it was actually the parents-in-law who wanted Xaoen gone the most even going so far as to threaten to kill themselves (what the actual fuck btw!?!?!) if the father didn't divorce the wife for giving him a girl. Father actually stood by his wife despite all the abuse he had to endure (although, again, don't wanna give him too much credit) but he probably started resenting Xiaoen because it. Or he resented her from the beginning, but again, he resented her because he was brought up in the culture that heavily favored male children over female children (for more info, you can research femicide in China that goes back 2000 years).
Hongqin (mom) did perpetuate patriarchy but she didn't do it because she agreed with it, but because she was a woman and that meant that she had to submit. She didn't care that Xiaoen was a girl but she knew that she would never be able to provide her with happy life, especially after they move away and she loses seemingly the only support network she had. In her mind, she also never really had a choice. Niu (father) saved her life, he stood by her against his parents and was abused for it. She couldn't do it to him. In the end, she was forced to make a decision and she made the hardest decision a parent could make, thinking it was the right choice because the new family would be able to give Xiaoen the life she never could. Hongqin encapsulates all this better than this comment ever could with a poingnant statement: "Although If I could choose, I've thought before... That I would rather choose to have not ever been a woman in the first place."
I'm glad that Hongqin didn't just stand up but stood up hard. She didn't just stand up for her child, she stood up for her self, realizing that this was the right decision all along. She thought that submitting would be better for everyone so she did, but the system upheld by tradition and bigotry was threatening to take another child from her. Submitting to it was never the answer but opposing it is hard and scary and most people are not strong enough to do it.
Anyways, good for Hongqin for standing up for herself and her daughters. What's enough is enough. She should devorce that bigoted wanker and move to Peachtown to be with her daughter, try to repair her relationship with the other one and to reconnect with her friends. Bless these women and the father can go to hell!
